It is known that existing geographic routing cannot maintain its capability in sparse networks compared to that in dense networks. Furthermore, mobile environments worsen the performance of greedy forwarding based routing. To become a practical protocol candidate, it is necessary to sustain stable performance irrespective of a network topology and mobility.(More)
— Vehicular networks have traditionally focused on the real-time delivery of critical control messages for safe car operation. Unfortunately, the real-time requirements often cripple the development of flexible car applications by tying the application network stack to underlying physical networks. While popular real-time vehicular networks guarantee the(More)
MuSI, a gene that corresponds to a domain that contains the rubber elongation factor (REF), is highly homologous to many stress-related proteins in plants. Since MuSI is up-regulated in the roots of plants treated with cadmium or copper, the involvement of MuSI in cadmium tolerance was investigated in this study. Escherichia coli cells overexpressing MuSI(More)
Among the various kinds of actuations for biomimetic robots, the electromagnetic actuation (EMA) method has been regarded as the one with the most potential. This paper proposes a jellyfish-like swimming mini-robot actuated by an EMA system in three-dimensional (3D) space. The jellyfish-like mini-robot has four flexible fins, each of which is equipped with(More)
